Description
The Spallation Neutron Source Linear accelerator is the highest power superconducting hadron linac in the world. Along with this distinction comes the significant complication of deposited power from beam loss, exacerbated by the fact that the linac transports H-. This paper summarizes our understanding of beam loss in the SNS linac and highlights research being done to improve that understanding. The question of beam loss due to halo has motivated development of a detailed model fidelity project at the SNS Beam Test Facility, which includes unique phase space diagnostics for 4D-6D distributions, and high-dynamic-range 2D distributions.
